This 3-ingredient peanut butter pie is the kind of effortless dessert that earns a permanent place in warm-weather gatherings, potlucks, and family cookouts. With a creamy peanut butter filling, a ready-made cookie crust, and almost no prep work, it delivers big flavor for very little effort. It is especially handy when you need a chilled dessert that can be made ahead and served straight from the refrigerator.

Serve this pie well chilled on its own, or dress it up with a little whipped cream, a sprinkle of crushed cookies, or a drizzle of chocolate syrup if you want to stretch beyond the three-ingredient theme. It pairs nicely with hot coffee, cold milk, or iced coffee, and for a block party or barbecue spread, it fits right in alongside grilled foods, fruit salad, and other simple summer desserts.

Ingredients

1 prepared chocolate cookie crumb pie crust (9-inch)

1 cup creamy peanut butter
1 tub frozen whipped topping, thawed (8 ounces)

Directions

1. In a medium mixing bowl, stir the creamy peanut butter and thawed whipped topping together until fully combined and smooth, with no streaks remaining.

2. Spoon the peanut butter mixture into the prepared cookie crust and spread it evenly to the edges, smoothing the top with a spatula.

3. Refrigerate the pie for at least 2 hours, or until the filling is firm enough to slice cleanly. For a firmer texture, chill a little longer.

4. Slice and serve cold.

Variations & Tips

Chocolate Drizzle: If you do not mind adding a fourth ingredient, a light drizzle of melted chocolate over the top adds a nice contrast to the peanut butter and makes the pie look a little more polished for parties.

Freezer Pie Option: For a colder, firmer texture, place the pie in the freezer for 30 to 45 minutes before serving. This is especially useful on very hot days when you want neat slices.

Crunchy Peanut Butter: You can swap in crunchy peanut butter for part or all of the creamy peanut butter if you want a little texture in the filling. Just keep in mind the slices will look slightly less smooth.

Make-Ahead Tip: This pie is ideal for making a day in advance. Keep it covered in the refrigerator until serving so the filling stays fresh and the crust remains crisp.
